I would like to spend some more time and effort on photo editing. The 13 inch screen on my Dell XPS laptop is good quality but rather small for use of Lightroom. I am thinking of getting a good desktop monitor, say 24 inch for photo editing and general use. There is a bewildering choice out there and it's hard to get an idea of the sweet point of price vs performance.

The more expensive monitors boast of things I don't fully understand the benefit of like different colour gammuts etc. My old A3+ photo printers is dead and drivers not available for current Windows, I will get a good replacement sometime in the future, so although ability to colour match is not needed now it will be later.

My laptop will display 1920x1080 but can support monitors with much higher resolutions - Will these higher resolutions be beneficial on a 24 inch monitor?
